82Atomic nucleus — A figurative depiction of the helium 4 atom with the electron cloud in shades of gray. In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom …
83Pentaquark — A pentaquark is an hypothetical subatomic particle consisting of a group of five quarks (compared to three quarks in normal baryons and two in mesons), or more specifically four quarks and one anti quark (hence it has baryon number 1) and is… …
84Loschmidt's paradox — Loschmidt s paradox, also known as the reversibility paradox, is the objection that it should not be possible to deduce an irreversible process from time symmetric dynamics. This puts the time reversal symmetry of (almost) all known low level… …
85List of physical quantities — This is a list of physical quantities.The first table lists the base quantities used in the International System of Units to define the physical dimension of physical quantities for dimensional analysis. Note that the angle and solid angle are… …

88Hyperon — In particle physics, a hyperon is any baryon containing a strange quark, but no charm quarks or bottom quarks.Properties and behavior of hyperonsBeing baryons, all hyperons are fermions. That is, they have half integer spin and obey Fermi Dirac… …
89Uranium-uranium dating — is a radiometric dating technique utilizing the comparison of two isotopes of uranium (U) in a sample: 234U and 238U. 234U/238U dating is one of several radiometric dating techniques exploiting the uranium radioactive decay series, in which 238U… …
90Chiral color — In particle physics phenomenology, chiral color is a speculative model[1] which extends quantum chromodynamics (QCD), the generally accepted theory for the strong interactions of quarks. QCD is a gauge field theory based on a gauge group known as …
